  1. Planting trees adds shade and can make homes for birds. (correct answer)
  2. Planting trees makes the ground covered with litter and cans.
  3. Planting trees makes the stream lower because water disappears.
Explanation: This tests positive changes. Trees give shade and homes to birds. Planting trees helps nature grow. Trees make places better!

Question 3

People cut a forest for a parking lot. How is nature impacted?

  1. Cutting trees and paving removes homes for animals and shade. (correct answer)
  2. Cutting trees makes the forest cooler and gives more shade.
  3. Cutting trees only changes the weather far away, not here.
Explanation: This asks about big changes to land. Cutting down a forest takes away animal homes. Hard parking lots get very hot without trees.

Question 4

Neighbors make a garden in an empty lot. What change happens?

  1. A garden adds plants and can bring bees and butterflies. (correct answer)
  2. A garden makes the street air dirty with black smoke.
  3. A garden means the lot stays bare dirt with no plants.
Explanation: This is about making habitats. Gardens have flowers that bees and butterflies love. The plants give them food and homes.

Question 5

People build houses on a field. How do they change the land?

  1. Building houses removes plants and animals lose their homes. (correct answer)
  2. Building houses makes the pond water cleaner and clearer.
  3. Building houses does not change the land or plants at all.
Explanation: This asks how people change the land. When we build houses, we dig up grass and flowers. Animals that lived there must find new homes.

Question 6

In the park, people litter. How does this change the environment?

  1. Littering makes the park dirty and can hurt animals. (correct answer)
  2. Littering makes the air smoky from car exhaust.
  3. Littering means people are playing games at the park.
Explanation: This asks about cause and effect. When people drop trash in the park, it makes the ground messy. Animals might eat the trash and get sick.

Question 7

At school, kids plant trees. How does planting affect the environment?

  1. Planting trees makes more trash on the ground at school.
  2. Planting trees adds shade and gives birds places to live. (correct answer)
  3. Planting trees makes the stream dry up because of cars.
Explanation: This asks about helping nature. Trees give us cool shade on hot days. Birds can build nests in the branches.

Question 8

How does littering change the park environment?

  1. Littering makes the park dirty and can hurt animals nearby. (correct answer)
  2. Littering makes the air smoky from car exhaust on streets.
  3. Littering makes trees grow taller and give more shade.
Explanation: This tests cause and effect. Littering makes parks dirty and unsafe. Trash can hurt animals who might eat it. Keep parks clean for everyone!

Question 9

Sprinklers run all day. What happens to the nearby stream water?

  1. Using too much water can make the stream lower for fish. (correct answer)
  2. Using too much water makes more trees grow without rain.
  3. Using too much water makes the playground covered in trash.
Explanation: This asks about using water wisely. When sprinklers use too much water, less water goes to the stream. Fish need water to live in.

Question 10

How do many cars on streets affect the air?

  1. Many cars make exhaust, and the air becomes less clean. (correct answer)
  2. Many cars plant trees, giving birds new nests and shade.
  3. Many cars make the park cleaner by picking up all trash.
Explanation: This asks about pollution effects. Cars make dirty smoke called exhaust. Too many cars make air hard to breathe. Walking helps keep air clean!

Question 11

School plants trees in the yard. What changes in the environment?

  1. Planting trees adds shade and bird homes in the yard. (correct answer)
  2. Planting trees makes the yard have more trash on ground.
  3. Planting trees makes the air smoky from car exhaust.
  4. Planting trees removes water from the stream until it dries.
Explanation: This question tests kindergarten understanding of identifying ways people affect the local environment (K-ESS3-3: Communicate solutions that will reduce the impact of humans on the land, water, air, and/or other living things in the local environment). People affect (change or impact) the environment in many ways, both negative and positive. Negative impacts include: Pollution - littering makes areas dirty and can harm animals; cars create air pollution; trash in water pollutes streams/ponds. Habitat destruction - building removes natural areas; cutting trees eliminates animal homes; paving covers soil. Resource overuse - using too much water reduces water in streams; wasting resources depletes what's available. Positive impacts include: Planting - adds trees, gardens, green spaces; creates animal habitat; provides shade and beauty. Protecting - keeping areas clean; not littering; preserving natural spaces. Creating habitats - birdhouses, butterfly gardens, protected areas. Understanding cause-effect: People's actions (littering, building, driving, planting, protecting) cause environmental changes (pollution, habitat loss, resource depletion, or improvements). Recognizing impacts helps us make better choices. This stimulus shows school planting trees in the yard, demonstrating positive environmental action. Observable environmental impact: trees added provide shade and create homes for birds. Before and after shown: yard was bare, now has trees providing shade and habitat. Connection visible: human action of planting causes environmental improvement of added shade and animal homes. Choice A is correct because it accurately identifies the environmental impact shown. Planting trees affects environment by adding shade for cooling and creating homes where birds can nest. The answer connects human action of planting to observable environmental consequence of habitat creation and shade provision. Impact described is appropriate to action shown, recognizes positive environmental change, shows understanding of trees' multiple benefits. Choice B is incorrect because it describes negative impact (trash) when planting is positive action. Choice C is incorrect because it confuses tree planting with car pollution, unrelated impacts. Choice D is incorrect because it suggests trees harm streams when they actually help by preventing erosion and providing shade. To help students identify environmental impacts: Use positive action examples - show before/after of tree planting, garden creation, habitat building. Discuss multiple benefits: 'Trees give us shade to stay cool. Birds build nests in branches. Squirrels find food and homes.' Demonstrate shade with flashlight and toy tree, show how shadow provides cool spot. Practice identifying positive impacts: 'When we plant flowers, butterflies come. When we add trees, birds have homes.' Create 'helping environment' chart showing positive actions and benefits. Take class outside to observe trees - look for bird nests, feel shade difference, see animals using trees. Use cause-effect for positive actions: 'If we plant trees, then birds have homes and we have shade.' Compare positive and negative impacts: planting trees (helps) versus cutting trees (harms). Make it personal: 'How do trees help our playground? What animals have you seen in our trees?' Watch for students who only recognize negative impacts or don't see how planting helps animals. Emphasize: people can help environment; planting adds homes and food for animals; trees provide many benefits; we can make environment better through our actions.

Question 12

School plants trees. What change happens in the schoolyard?

  1. Planting trees adds shade and can make homes for birds. (correct answer)
  2. Planting trees covers the yard with trash and plastic bottles.
  3. Planting trees makes the stream run out of water completely.
  4. Trees grow only at night, so the yard never changes.
Explanation: This question tests kindergarten understanding of identifying ways people affect the local environment (K-ESS3-3: Communicate solutions that will reduce the impact of humans on the land, water, air, and/or other living things in the local environment). People affect the environment in many ways, both negative and positive, such as planting trees that add shade and bird homes, contrasting with negative impacts like littering that dirties areas. This stimulus shows a school planting trees in the schoolyard, resulting in added greenery that provides shade and habitats, observable as a change from bare to vegetated space. Choice A is correct because it accurately identifies the environmental impact shown: planting trees affects the environment by adding shade and making homes for birds, connecting the human action to the positive consequence of habitat creation. Choice B is incorrect because it attributes a negative impact like trash to planting, which kindergarteners might confuse if they mix up positive and negative effects. To help students identify environmental impacts, plant a small garden in class and discuss 'If people plant trees, then birds have homes and shade.' Use before-and-after pictures of bare yards turned green, compare positive and negative impacts on a chart, and make it personal by asking what they can plant to help their schoolyard.

Question 13

Look at people cleaning up. How does it affect the park?

  1. People clean up trash, and the park becomes cleaner for animals. (correct answer)
  2. People clean up trash, and more trees are cut down nearby.
  3. People clean up trash, and the pond water gets filled with plastic.
Explanation: This tests understanding helpful actions. Cleaning up trash makes parks nicer. Clean parks are better homes for animals.

Question 14

What happens to the air when many cars drive by?

  1. Many cars drive, and the air gets hazy from exhaust smoke. (correct answer)
  2. Many cars drive, and the stream gets lower with less water.
  3. Many cars drive, and the ground grows more flowers everywhere.
Explanation: This asks about cause and effect. Cars make exhaust smoke when they drive. The smoke makes the air hazy and hard to see through.

Question 15

What environmental change do people cause by paving a parking lot?

  1. People pave land, and plants are removed so the area gets hotter. (correct answer)
  2. People pave land, and more birds build nests in new trees.
  3. People pave land, and the air becomes cleaner with less exhaust.
Explanation: This asks about paving effects. Paving covers plants with hard surfaces. Dark pavement gets very hot in the sun.

Question 16

How do people change an empty lot by making a garden?

  1. People make a garden, and more plants and butterflies appear. (correct answer)
  2. People make a garden, and the air turns gray from car smoke.
  3. People make a garden, and the stream dries up from no rain.
Explanation: This asks about positive changes. Gardens have many plants and flowers. Butterflies come to gardens to visit the flowers.

Question 17

How does cutting trees change the forest environment?

  1. People cut trees, and animals lose homes and shade is gone. (correct answer)
  2. People cut trees, and the air becomes cleaner with less exhaust.
  3. People cut trees, and the park gets more swings and slides.
Explanation: This tests understanding habitat loss. Trees are homes for many animals. When trees are cut, animals lose homes and we lose shade.

Question 18

How does building houses change the land environment?​

  1. People build houses, and trees are cut so animals lose homes. (correct answer)
  2. People build houses, and the park becomes cleaner with no trash.
  3. People build houses, and rain makes the land change by itself.
Explanation: This tests understanding consequences. When people build houses, they cut down trees. Animals who lived in the trees lose their homes.

Question 19

What impact do people have when they throw trash in a pond?

  1. People throw trash, and pond water gets polluted and unsafe. (correct answer)
  2. People throw trash, and more fish appear because water is cleaner.
  3. People throw trash, and trees are cut down far away.
Explanation: This asks about pollution effects. Trash in water makes it dirty and polluted. Polluted water is not safe for fish or people.

Question 20

What happens when people use too much water at home?

  1. Too much water use can lower streams for fish and plants. (correct answer)
  2. Too much water use makes the playground fill with more swings.
  3. Too much water use makes the sky hazy from car pollution.
Explanation: This asks about cause and effect. Using too much water takes it away. Fish and plants need water too. Save water to help nature!
